Abstract

In a lock fitted with a rotary latch ( 30 ), a detent ( 40 ) is provided that can engage inside a preliminary catch and inside a main catch ( 32 ) of the rotary latch ( 30 ). The rotary latch ( 30 ) receives a locking part and can be transferred either manually or by means of a motor between an open position, a preliminary catch position and a main catch position ( 30.2 ). The motor-driven displacement ensues via a closing aid or an opening aid. In order to obtain a space-saving design, the invention provides that a locking lever ( 10 ) is eccentrically mounted on the rotary latch ( 30 ) and is held in a central position by an impulse spring whereby functioning as a closing aid. A stationary, rotationally mounted driving element ( 50 ) serves an opening aid, and an opening lever ( 20 ) is rotationally mounted on this driving element. This opening lever ( 20 ) is also held in a central position by an impulse spring. The locking lever ( 10 ) projects inside the preliminary catch position always in the path of rotation of the eccentric ( 21 ) and is entrained in one direction when the motor turns. In an analogous manner, the opening lever ( 20 ) projects into the main catch position ( 30.2 ) in the path of rotation of the eccentric ( 21 ) and is entrained in the opposite direction during rotation ( 23 ). The entrained opening lever ( 20 ) pushes, via the driver ( 50 ), the detent ( 40 ) from the rotary latch ( 30 ), whereby the door is opened by a motor.

Description

LOCK FOR DOORS OR LIDS ON VEHICLES}

The invention relates to a lock of the type set forth in the preamble of claim 1. The lock is usually placed in the area of the door or lid and has a rotary latch. The door holder is provided with a locking member that enters into the rotary latch upon manual locking of the door or lid and rotates the rotary latch from the opened position to which the elastic force is applied to the preliminary locking position. On the contrary, the lock may be disposed on the door holder, and the locking member may be disposed on the door.

The preliminary locking position of the rotary latch is fixed by a rotatably mounted fixed detent, which depresses towards the rotary latch and enters into the preliminary latch of the rotary latch. There is also provided a reversible driveable motor with a slave control for switch on / off. The motor interacts with a motor driven opening aid as well as a motor driven locking aid for the door or lid, and more particularly through a transmission with at least one eccentric. Through the locking aid, the rotary latch is passed from the eccentric to the main locking position, which is also fixed by the detent. In the main locking position the detent enters the main locking portion provided in the rotary latch.

In a lock (WO 98/27301) with a motor driven locking / opening assistance device in which the transmission has two working paths, the transmission member is arranged to enable pivotal movement between the two working paths. Although the locks have proven useful, they require a lot of space and are expensive.

Known locks of the type mentioned in the preamble of claim 1 (DE 101 33 092 A1) are produced at low cost compared to the prior art. In this known lock the transmission of the motor acts on two eccentrics while still in engagement, one of which interacts directly with the rotary latch and the other with the detent. The eccentrics and the transmission members of the eccentrics should be spaced apart so that during rotation of the eccentric acting as an auxiliary locking device the other eccentric moves in the free rotation state with respect to the detent, which is an opening aid. The opposite applies to other eccentric bodies. To this end, sufficient space must be provided within the lock. If the electronic control device, motor and / or power supply fail during the locking process between the preliminary locking position and the main locking position, the occupant is trapped inside the vehicle even in an externally mechanically induced emergency operation mode. In such a lock, the rotary latch is fixed, for example, in the so-called "overtravel position" by the eccentric body even when the detent is mechanically actuated.

Also known from US Pat. No. 4,395,064 is a method of rotatably mounting the locking lever and the opening lever to the rotary latch or detent eccentrically. However, the lever does not have an intermediate position that can be predetermined by the spring or the control surface.

From DE 37 21 274 T2 and EP 0 478 013 B1 it is basically known how to apply a compressive stress to the lever by means of a pulse spring. However, locking locks and opening aids are not provided in locks according to these documents.

It is an object of the present invention to develop a reliable lock of the type mentioned in the preamble of claim 1, which can be designed in a relatively space-saving manner and which can be driven even in the event of a failure of the electronic device. This object is achieved through the measures described in claim 1, which describes the specific meaning of the measures below.

In both the locking aid and the opening aid, the eccentric body (s) only acts indirectly on the rotary latch or detent. The locking lever of the locking assist device rotatably mounted to the rotary latch and the opening lever of the opening aid mounted to the rotatable fixed drive body interact with each eccentric body. Both the locking lever and the opening lever are fixed in the intermediate position defined by the respective pulse springs. In the intermediate position, the eccentric body interacts with the locking lever only in the preliminary locking state, and when the eccentric body rotates in one direction, the rotation latch is switched to the main locking state. When the rotary latch is in the main latched state or in the open state, the lock lever is placed outside the driven path of the eccentric body and is not operated.

The same applies to the case of the opening lever in which the working end is aligned with the rotation path of the eccentric in the main locking state. In this case, the eccentric body may apply torque to the drive unit when the eccentric body rotates in the opposite direction despite the free movement of the opening lever. As a result, the detent is driven and released from the main latch position of the rotary latch. The rotary latch is then switched to the open state by the inherent spring load. In order for the rotational position to have sufficient time for the operation, a profile and a corresponding profile between the opening lever and the eccentric are provided. The opening lever is disposed by the driving body in such a manner that, in the open state as well as in the prelocking state, when the eccentric body rotates in one direction, the opening lever pivots away in response to the action of the pulse spring and does not apply driving pressure to the driving body. After passage of the eccentric, the opening lever is returned to the intermediate position by the pulse spring. In the opposite direction of rotation, the opening lever is caught by the eccentric to pivot the drive and detent again. In general there is a free gap between the shoulder of the drive and the corresponding shoulder of the detent in both the open and prelocked states.

If two inherent eccentrics are to be used for the locking aid and the opening aid, in the present invention the spaces in the lock are saved by placing the eccentrics closely next to each other. Alternatively, the manner in which the two eccentric bodies are axially aligned to the common transmission output of the motor is also very space-saving.

Further measures and advantages of the invention are set forth in the dependent claims, the figures and the following description. In the drawings an embodiment of the invention is schematically illustrated in various positions, more precisely in a plan view from the inner surface of the trunk lid, based on the essential lock parts, and the lock housing is omitted.

1A to 8A show only the lock parts actuated through the locking lever from the first eccentric. Other lock parts arranged in the plane in front of them are omitted in FIGS. 1A to 8A and only their positions are indicated by dashed lines, but are shown as entities in FIGS. 3B to 8B where the opening aid works. 3b to 8b show the opening lever controlled by the second eccentric body. In FIGS. 3B-8B the locking levers of FIGS. 1A-8A are largely omitted and are shown only in FIG. 3B.

1A is an open state of a lock fixed to a trunk lid of a vehicle, which appears when the lid is opened;

2A is a preliminary locking state when the lid is partially closed.

3a + 3b are the initial stages of operation of the locking aid.

4A shows the final stage of the locking aid, with the lock reaching the so-called “overtravel position”.

Fig. 5A shows the main locking state of the lock part, which appears when the lid is closed in accordance with the regulations.

6a + 6b show an initial stage of a motorized opening aid that is operated in a lock while the rotary latch is still in the main latched position.

7A shows an intermediate stage of the opening aid, in which the rotary latch has already been released from the detent, but is still fixed in the main locking position by the locking lever and the eccentric of the locking lever.

8A + 8B show that the motor is driven with the open lever still secured by its eccentric body, but with the lock lever released by its eccentric body, the rotary latch returns back to the open position (lead open) of FIG. 1A. End position of the locking device.

9A is an emergency situation where the trunk lid must be opened manually as the motorized locking aid fails.

FIG. 10A is an emergency situation of FIG. 9A supplemented by manual drive to return the locking aid to the initial position where the lock is again ready for future motor drive.

On the first fixed shaft 33 of the lock housing, not shown in detail, a rotary latch 30 having a profile notch 34 for receiving the locking member 35 is mounted. The locking member 35 may be mounted to a door post which is formed as a bolt or shackle pin and fixed in place. In contrast, the lock housing is mounted to the movable lead, which is not shown in the figures as already mentioned. The rotary latch 30 is subjected to a spring load (not shown in detail) which acts in the direction of the arrow 36 in FIG. 1A. The spring load 36 acts to keep the rotary latch pressed against the stationary stopper 37 in the housing. The rotary latch is then placed in the "open position" indicated by the auxiliary line 30.0 in FIG. 1A, in which the locking member 35 is released. The lid can then be opened or closed.

When the lid is closed, the locking member 35 enters into the notch 34 according to FIG. 2A, and the rotary latch 30 is preliminarily engaged with the stop end 41 of the detent 40 provided to the rotary latch 30. It rotates in the direction of the rotation arrow 38 of FIG. 2A until it approaches part 31. The detent 40 is also mounted to a shaft 43 fixed in the lock housing and under the action of a spring load, which moves in the direction of the force arrow 42 with respect to the rotary latch 30 by the spring load. In FIG. 2A the rotary latch 30 is in the "preliminary locking position" indicated by the auxiliary line 30.1. In the open position of FIG. 1A, the stop end 41 of the detent 40 is elastically supported at one circumferential point 39 of the rotary latch 30.

Starting in the preliminary locking position of FIG. 2A the motorized locking aid is now active. The locking aid consists of a motor (not shown in detail) with an electrical control device and a transmission, on which the first eccentric body 11 is mounted. The motor can be reverse driven. In the preliminary locking position of FIG. 2A, the eccentric body 11 rotates in the direction of the rotation arrow 13. The direction of rotation 13 is indicated clockwise in the figure. In this case, the eccentric 11 hits the collision end 14 of the locking lever 10 pivotally mounted at the link point 15 of the rotary latch 30. The locking lever 10 is loaded with a spring load against the rotary latch 30 by a pulse spring (not shown in detail), which spring load causes the locking lever 10 to be marked by the auxiliary line 10.0 in the "middle position". Secure in. The action of this pulse spring is illustrated by arrow pair 16 in FIG. 3A. Rotating the output shaft 12 in the opposite direction 23, ie counterclockwise as described in relation to FIG. 3B, causes the locking lever 10 to rotate to the operating point 10.1 indicated by dashed lines in FIGS. 3A and 3B. The result will be back to the intermediate position 10.0 by the pulse spring 16 after passage of the eccentric body 11. During the rotation 13 described above, ie clockwise rotation, when the eccentric body 11 hits the impingement end 14 of the locking lever 10, the locking lever is subjected to the torque indicated by the arrow 28 in FIG. 3A. Is applied to the rotary latch 30.

The action of the rotary torque 28 is shown in FIG. 4A. The rotary latch 30 was rotated further by the angle indicated by the motor at " 18 ". In the further rotation 18 the eccentric 11 rolls over the collisionally formed collision end 14. As a result of the further rotation 18 the stop end 41 of the detent 40 subsequently enters behind the main catch 32 provided in the rotary latch 30. The main catching portion 32 here is formed in the profile contour of the notch 34 used to receive the locking member 35. In order to allow the detent 40 to safely enter behind the main catch 32, an excessive stroke of the rotary latch, referred to as “overtravel” by the rotation 18 of the rotary latch, is implemented. This overtravel determines the "overtravel position" of the rotary latch 30, indicated by the auxiliary line 30.3 in FIG. 4A. In the overtravel position 30.3 an air gap 44 is formed between the main catching portion 32 of the rotary latch and the stop end 41 of the detent.

Within the lock is provided a fixed stopper 57 which interacts with the shoulder 57 of the rotary latch 30 in the "final position" which will be described in more detail with reference to FIG. 10A. In the overtravel position 30.3 there is also an air gap 56 between the stopper 47 and the shoulder 57.

The eccentric body 11 further implements the clockwise rotation 13 of the figure, first releasing the impact end 14 of the locking lever 10. Then, the rotary latch 30 is slightly reversed by the spring load 36 until the main latch portion 2 of the rotary latch is supported by the detent end 41 of the detent. This process is illustrated in Figure 5a. The rotary latch is now in the “main latching position” indicated by auxiliary line 30.2 in FIG. 5A. The main locking position 30.2 is also indicated in FIG. 4A. The locking member 35 moves from the preliminary locking position (corresponding to the preliminary locking position in FIGS. 2A and 3A) indicated by the dashed line and the auxiliary line 35.1 in FIG. 5A to the position "35" by the distance "19". The position is indicated by auxiliary line 35.2 in FIG. 5A. The lock-mounted lid was pulled by distance "19" against the action of the resilient door seal. When the eccentric body 11 reaches, for example, the "12 o'clock" point shown in FIG. 5A, preferably also in the starting position of FIG. 1A, the electrical control device turns off the motor. In Figure 5A the lid is locked according to the regulations.

The lock is also provided with a motorized opening aid for easy opening, starting from the main locking position 30.2 of FIG. 5A. The opening aid is controlled by the same motor and in the present invention even by the same transmission. For this purpose, the second eccentric body 21 shown in Fig. 6b is used, which is arranged in a different plane than the above-described first eccentric body 11, but in the present embodiment the same output shaft 12 Was fitted. As an alternative, the two eccentrics 11, 21 can be mounted to two different transmission elements of a motor arranged radially spaced from each other. When the authorized user turns on the motor via a switch or via a remote control, the operation of the opening aid is started, as a result of which the motor rotates in the opposite direction 23, ie counterclockwise, as already described in FIG. 5A. As already said, since the two eccentric bodies 11 and 21 are both mounted on the same output shaft 12, both the eccentric bodies rotate in the opposite direction 23, i.e. counterclockwise. At this time, the first eccentric body 11 implements the idle swing 10.1 of the locking lever 10 shown in the cut shape in FIG. 3b, which has already been described based on FIG. 3b, in which case the opening assistance as shown in FIG. 6b. Interact with other lock parts of the device.

The drive body 50 is attached to the fixed shaft 43 which is also an axis of the detent 40. The driving body 50 is spring-loaded toward the rotary latch 30 in the same direction as the detent 40 despite being disposed in a plane placed in front of the rotary latch 30. The detent 40 is disposed in the same plane as the rotary latch 30. The drive body 50 interacts with the protruding arm 46 of the detent 40 through a recoil lug 54. In the unloaded state, the drive body 50 is stopped at a limit stop (not shown in detail) due to the spring load 52, thereby causing the stop indicated by the auxiliary line 50.0 in FIG. 6B. Take a position. In the stop position 50.0 shown in FIG. 6B there may be an air gap 17 between the lug 54 and the arm 46.

An opening lever 20 is mounted at the link point 22 at the free end 51 of the drive body. The opening lever 20 is also subjected to the action of a pulse spring (not shown in detail), which action is indicated by arrow pairs 26 in FIG. 6B. The pulse spring 26 is used to hold the opening lever 20 in a fixed intermediate position, indicated by auxiliary line 20.0 in FIG. 6B. In the above-mentioned reverse rotation 23, the second eccentric 21 strikes the collision end 24 of the opening lever 20, and this process occurs in FIG. 6B. Upon further rotation 23 of the eccentric body 21, the release lever 20 and the drive body 50 are pushed out, as shown in FIG. 8B. The stopper 25, which is fixed in the lock housing, allows the opening lever 20 to rotate only a fixed amount from the intermediate position 20.0 in the opening phase, and is not driven by the eccentric 21, in particular during further rotation 23. Used to avoid The driving body 50 moves by an arbitrary angle 53 to the operating position indicated by the auxiliary line 50.1 in Fig. 8B. In the rotation 53 the shoulder 55 in the drive lug 54 drives the detent 40 via the corresponding shoulder 45 in the detent arm 46. As a result, the detent 40 is moved away from the rotary latch 30 by the spring load 42, and the detent end 41 of the detent is the main latch portion 32 of the rotary latch 30 shown in Fig. 6B. It is detached from). The rotary latch 30 is then rotated by the spring load 36 to the open position 30.0 shown in FIG. 8B, the open position 30.0 being fixed in the housing as already described in FIG. 1A. Is determined by At this time, the locking member 35 is pushed out of the rotary latch 30 and released in accordance with FIG. 8B. The lid is now released and can be fully opened.

6A to 8A show what action occurs in the area of the locking lever 10 during the lock opening step caused by the opening lever 20. In the figures, for the sake of clarity, the parts important for the inherent opening assistance device, namely the second eccentric body 21, the opening lever 20 and the driving body 50, are omitted. When the second eccentric 21 reaches the position of FIG. 6b during reverse rotation 23, the first eccentric 11, which is mounted on the same output shaft 12 of the transmission, is naturally shown in FIG. 6a. Go to location. The first eccentric 11 slides through the impingement end 14 of the locking lever 10 and cannot act on the detent 40 at this time. The detent 40 remains in engagement with the main catching portion 32, whereby the main catching position 30.2 is first and foremost guaranteed. This state changes only in the course of switching from Fig. 6B to Fig. 8B. In FIG. 7A, the intermediate position of the first eccentric body 11 is shown in the reverse rotation 23, in which only a part of the driving body 50 is shown, which is directly actuated by the opening lever 20. ) However, on the other end side, since the locking lever 10 is still supported by the first eccentric body 11, in Fig. 7a the rotary latch 30 is still in the main latching position 30.2 which coincides with Fig. 5a. In FIG. 7A, the stop end 41 of the detent 40 has already released the main latch 32 of the rotary latch, because the shoulder 55 of the drive stops through the corresponding shoulder 45. This is because the iron 40 has already been pushed out.

In FIG. 7A the first eccentric 11 first releases the locking lever 10 upon further rotation of the two eccentric bodies 11, 21. However, the second eccentric body 21 is mutually supported with the release lever 20. The released rotary latch 30 thus has a time sufficient to be reversed by the spring load 36 back to the original open position 30.0 shown in FIG. 8. The detent 40 is not exposed to the action of the spring load 42 until the second eccentric body 21 also releases the opening lever 20. This occurs upon further rotation of the output shaft 12 in the reverse direction 23. Upon reaching the "12 o'clock" -start position of FIG. 1A, the motor stops reverse rotation 23.

Fig. 3B also describes what action occurs in the locking parts of the opening aid when the output shaft 12 rotates in the direction " 13 " causing the lid closing action of the locking members of Figs. 1A to 5A. It is. In this way, when the rotation is made in the clockwise direction 13, the opening lever 20 is operated by the pulse spring of the opening lever, and thus, the auxiliary lever (from the intermediate position 20.0) indicated by the auxiliary spring in FIG. Rotate freely to the angular point marked 10.1). This is indicated by each "27" in FIG. 3B. This process has no effect on the detent 40 engaging the rotary latch 30. Although only the preliminary locking position 30.1 is shown in FIG. 3B, this also applies to the main locking position when both eccentric bodies 11 and 21 are driven jointly in the rotational direction 13, that is, clockwise.

The lock according to the invention allows access to the vehicle in which the trunk lid is closed even if the motor and / or power supply fails after the preliminary locking position 30.1 has been reached. The case of such a motor failure is shown in FIG. 9A. In this embodiment, the eccentric body 11 is further rotated by a very small amount from the preliminary locking position shown in FIG. 3A, and the rotation shown by the dashed-dotted line by the locking lever 10 'shown by the dotted line during the further rotation. Pass the pivot position 30 'of the latch. The rotary latch 30 ', shown by the dashed lines, is in the intermediate position 30.5, indicated by the auxiliary line 30.5. The eccentric 11 can still rotate further in the direction of the rotation arrow, also indicated by a dashed line.

By manually closing the trunk lid against the action of the seal, the rotary latch 30 is moved to at least the overtravel position 30.3 of FIG. 4A or even to the “final end position” indicated by the auxiliary line 30.4 in FIG. 10A. . The end position 30.4 is determined by the rotary latch 30 hitting the stopper 47 fixed by the shoulder 57 of the rotary latch, as shown by the dashed-dotted line in FIG. 10A. The detent 40 can then be released from the main locking position 32 by mechanical emergency operation (not shown in detail). As a result, the rotary latch 30 is reversed to the open position 30.0 by the spring load 36, which is indicated by the rotary arrow 29 in FIG. 9A. In the open position 30.0 of FIG. 9A, the rotary latch 30 has released the locking member 35. The trunk lid is now open.

In this way, when the rotation latch is reversed from the intermediate position 30.5 to the open position 30.0, the locking lever 10 strikes the protruding region 48 of the eccentric body 11. The protruding region 48 prevents the locking lever 10 from passing the eccentric body. The locking lever 10 rotates to the emergency position 10.2 in response to the force 16 of the pulse spring in FIG. 9A, in which the locking lever 10 is separated from the associated eccentric body 11. Then, the motor drive is triggered again, so that the additional rotation of the locking lever 10 smoothly passes the eccentric body 11.

As shown in Fig. 9A, in accordance with the aforementioned emergency situation, the rotary latch 30 is in the open position 30.0 defined by the fixed stopper 37, but the locking lever 10 is in the middle of Fig. 1A in Fig. 9A. It is in the emergency position 10.2 rotated relative to the position 10.0. In FIG. 9A the locking lever 10 is supported by the above-described eccentric body region 48 by its pulse spring load 16. Even if the fault of the motor persists in FIG. 9A, the lock according to the present invention can be returned to the initial drive ready state of FIG. 1A again in the following manner. This will be explained based on FIG. 10A.

The trunk lid starts manually in FIG. 9A and is manually closed again. At this time, the locking member 35 enters into the rotary latch 30, and the rotary latch rotates again in the direction of the overtravel position 30.3 and the end position 30.4 as shown by the arrow 49 in FIG. 10A. In FIG. 10A, the position of the rotary latch indicated by the auxiliary line 30.6 is sufficient to release the locking lever 10 in advance. That is, in FIG. 10A the lever 10 is placed through the link point 15 to the rotary latch 30 so that its stop end 14 is outside the rotary travel of the eccentric body 11 indicated by the rotation arrow 58. It was back to the extent. Initially the locking lever 10, which was in the emergency position 10.2 shown in dashed line in FIG. 10A, automatically rotates back to the intermediate position 10.0 by the pulse spring load 16. The trunk lid is opened in accordance with the return action of this locking lever according to FIG. 10A, where the detent 40 is disengaged from the rotary latch 30 by resuming mechanical emergency drive (not shown in detail), whereby the lock is automatically Is switched back to the initial state according to FIG. Then, regardless of the time point at which the motor of FIG. 10A continues to rotate in the direction of the rotation arrow 58, the eccentric body 11 rotates back without any problem to the predetermined initial position of FIG. In this further rotation 58 of the eccentric 11 no collision with the locking lever 10 occurs.
